Very few teams have a higher average age for players than the New Orleans Saints, per Jimmy Kempski of Philly Voice. In fact, just one: the Atlanta Falcons (26.9 years). The Chicago Bears are tied with the Saints (26.7 each), making them the three oldest teams in the NFL, on average.
But context matters here. The Saints may be ranked all the way down the list at No. 30, but teams listed near the middle of the pack like the Pittsburgh Steelers, New York Jets, and Philadelphia Eagles (tied for No. 17) have an average age of just 26.
